Description:
a tiny part of the lens library with no dependencies; profiling libraries
This is an extract from the lens package with no dependencies. It's not a toy lenses library, unsuitable for “real world”, but merely a small one. It is compatible with lens, and should have same performance. It also has better documentation. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
